Patent JP-S58147723-A (JP)
Title: Camera
Inventor: TOUJIYOU AKIHIKO
IPC: G03B7/16
Filed: 1982-02-26
Abstract: PURPOSE:To execute flash photographing whose S/N is good, by shortening a signal reset time of an image pickup means, at the time of flash photographing. CONSTITUTION:When a main capacitor of a flash device FL is charged, and an output of an AND gate AG1 is inverted to a high level by a high level output corresponding to completion of preparations of flash light emission, and a high level output of a synchronizing and controlling circuit SGC, an output of a voltage generating circuit VG is selected instead of an output of a differential amplifier DF through a selecting gate SGA. As a result, by a duty ratio controlling circuit DC, signal integration by a signal integral type image pickup means IS is inhibited in a high level output period of the circuit VG. By this inhibition, a signal reset time of the means IS is shortened and flash photographing whose S/N is good is executed without being influenced by a dark current.

Title: Regenerative rotary heat exchanger
Inventor: SASAKI MASASHI
IPC: F28D19/04
Filed: 1982-02-27
Abstract: PURPOSE:To enable to protect an elastic member against heat, by making the outer diameter of a sealing means smaller than that of a core so that the core is spaced apart from the elastic sealing means disposed on the outside of the core, and passing a low-temperature fluid through a core passage formed outside of the sliding portion of the sealing means. CONSTITUTION:A sealing means 20 has an outer diameter smaller than that of a core 21 and is held in contact with the core 21 on both sides thereof. The sealing means 20 covers the entire periphery of the core 21 at its lower surface while it covers one half of the periphery on the side of an outlet passage 7 at its upper surface. In the drawing, a numeral 22 represents an annular passage through which a low-temperature fluid is passed. Thus, an annular passage 22 is formed by an annular portion of the core 21 disposed around the outside of the sealing means 20. Since the low-temperature fluid is passed through the portion of the core 21 forming the annular passage 22, the core 21 is cooled always. Further, since the annular passage thus cooled is interposed between the elastic sealing means 20 and the core 21, the temperature at the portion where an elastic member 2 is held in contact with the core 21 can be kept almost equal to the temperature of the low-temperature fluid by the cooling and heat-insulating function of the annular passage.

IPC: G11B5/84
Filed: 1985-02-21
Abstract: PURPOSE:To obtain the titled magnetic disk whose modulation is close to 1 by sticking a flexible disk on a substrate and then heat-treating the assembly. CONSTITUTION:A flexible disk 2 consisting of a carrier 4 and a magnetic layer 5 is stuck through a space 3 on one or both surfaces of a substrate 1.

Abstract: PURPOSE:To make it possible to easily remove a mask as well as to simply carry out effective masking when a WC layer is partially deposited on the surface of a metallic base material, by using fluororesin as a masking material. CONSTITUTION:The surface of a metallic base material 1 obtd. by forming a plated Ni-P layer 3 on a metallic base 2 of steel or the like is degreased and cleaned so as to improve the adhesion of fluororesin to the surface.

IPC: G01F1/32
Filed: 1979-03-20
Abstract: PURPOSE: To achieve the higher measurement accuracy of the flow rate of the air flow sensor even when there are pulsating flows in fluid by changing the shape of the through-hole inlet of a Karman vortex street generating body thereby making the flow in the through-hole always in the fixed direction.  
     CONSTITUTION: Guide plates 5, 6 are provided on the inside wall surfaces of the opening of the through-hole 2a of a vortex generating body 2; the guide plate 5 being secured on the upper stream inside wall surface 2' a side and the guide plate 6 on the lower stream inside wall surface 2" a side respectively and the front end parts of the guide plates 5, 6 being protruded from the top and bottom surfaces of the vortex generating body. A flow-aligning grating 10 is provided on the upper stream side of the vortex generating body 2. When with such constitution the fluid passes through the aligning element 10 from the direction of the arrow X then passes through the vortex generating body 2, the fluid entering the through-hole 2a is limited in the arrow Y direction by the action of the guide plates 5, 6. Hence, the velocity of flow v a  in the through-hole 2a becomes the change in the magnitude of the flow of always a fixed direction and the waveform of the heat ray output V has the frequency equal to the velocity of flow v a  and even at the time of pulsating flow it has the similar relations, thus the air flow rate may be measured with high accuracy.

Abstract: PURPOSE: To remove switching time for an external address and an internal counter output and to speed up the operation of an address buffer by reducing the 1st clock to a H level and also the level at refreshing to the H level.  
     CONSTITUTION: At normal status, the output bar PRF of a generator 1 is H and a N 21  point through a transistor Q 41  is also H level (Vcc-Cth). In this status, a clock ϕ 0  is inputted to an address buffer 7 through a transistor 42 as a clock ϕON. At that time, N 21  increases more than Vcc by the bootstrap effect of the transistor 42 and the level of ϕ 0  is directly transmitted as ϕON. At refreshing status, reversely to said procedure the output PRF of the generator 1 is turned to H and the clock ϕ 0  is outputted to the address buffer 7 as ϕOR through Q 44 .

Title: Transmission signal for high speed signal using printed circuit board
Inventor: ANDO MASAKAZU
IPC: H01P3/08
Filed: 1994-02-03
Abstract: PURPOSE:To obtain a transmission line through which a high speed signal is transmitted at high speed and low loss with an inexpensive board material by making holes between a signal line and a ground line to eliminate part of a dielectric material thereby producing cavities being parts of the dielectric material with a small specific dielectric constant. CONSTITUTION:Holes 8 are made to each part 3(S) at an interval of which each signal line 1 and each ground line 2 are spaced to eliminate part of a dielectric material 6 of a printed circuit board 7. A polyimide is adopted for a flexible printed circuit board material 7 and the holes 8 are made by the photo etching method. Thus, cavities 9 with a dielectric material being air whose dielectric constant is least are formed in the dielectric material between each signal line 1 and each ground line 2. Thus, the combined specific dielectric constant is decreased by forming the part whose dielectric is small by means of the cavities 9. As a result, the transmission line through which a signal is propagated at a high speed and a low loss is attained by decreasing the specific dielectric constant specific to the polyimide in a simulating way.

Abstract: PURPOSE:To suppress the inclination of an arm and to smooth the specified operation by inclining the central axis of the bearing of a presser plate in the reverse direction with respect to the acting direction of energizing force applied on the arm. CONSTITUTION:One brake arm 3 is turned with upper and lower rotary shafts 3a and 3b being supported with a bearing la of a presser plate l and a bearing 2a of a chassis 2.
